Rd. 24: A strange situation in SugaR 1-0 ShashChess:
33.exd5 +1.21  Rag6 -1.26 ("-" bad for mover here)
white's evaluations slowly increased while black's slowly decreased until:
45.Rc6 +2.75  f5 -0.74 , then
46.Rh6 +2.83  f4 -2.73 black suddenly realized it was lost though white knew for a long time.
SugaR drew as black in the reversed, inserted.

Arena calls the opening for this game pair A40 Sicilian: Accelerated Pterodactyl, 4.c4 (by transposition).

Stockfish as white does not attack black's advanced d-pawn. Instead it sacrificed a pawn with 17.c5.
SugaR says black's returning it with 20...b5? was a mistake. [Event "G/3'+1.5'' Apex 1GBh Sy.6"]

Same opening but as black Stockfish made a gambit with 9...Nf6 allowing white to gain a pawn with its 10.Qxd4.
After 14...f5 ShashChess returned the pawn with 15.Nd2 but black got good counter-play anyway and it was a short draw.

B45 Sicilian Taiminov: As white Stockfish gambits its h-pawn with 13.Qd2, 14.O-O-O; its already winning when it gambits its a-pawn with 26.b4!;  and with 30.Bc8!! it said "Mate in 25" - note the lightning TC.
